This article is for setting up "SentinelX Sharing" feature of COIN, which involves sharing your SentinelX with another user to earn 10% of what they collect while the shared SentinelX is nearby. If you are using a single SentinelX for 12x rewards, please see this article: Earning more with a SentinelX
Tap the + icon in the top right corner of the screen. Tap Referral Rewards, and tap SentinelX Sharing
The SentinelX Add Screen
Once you get to the add screen, the process is pretty straightforward. Press the button on your SentinelX or XY4+, then select its color and name it (who you will give it to or where you will put it).
There are two problems that can occur here:
a) There was more than one SentinelX or XY4+ button press detected (this will kick you out of the process, explain why and have you try again after 15 secs)
b) The SentinelX you have pressed is currently doing a bound witness and so COIN can't see it. You should to give it up to a minute to start advertising again (while pressing the button every 10 seconds).
Note: If you selected the incorrect color or need to rename your SentinelX, please see this article: How to rename and/or change the data for your paired SentinelX in COIN
Placing the Shared SentinelX
Once the SentinelX or XY4+ is added you can place it in a shared area (like at a train station) or give it to someone and any time geomining occurs with it in range, it has a chance to be selected for the 10% share of rewards.
If it is the only SentinelX or XY4+ in range then it will be selected 100% of the time. Only 1 device is selected per geomine for sharing.
How to see Rewards and How they are Delivered to Your Account

Please note: SentinelX Sharing Rewards only trigger for Geomining rewards greater than 0.01 COIN. Remines and Geomines on Device Change are not counted.
